Projector having tilted transmissive substrate and multicolor pixel modulator

A projector comprising:

• a light source device;
• a light modulation device adapted to modulate a light beam emitted from the light source device;
• a light transmissive substrate adapted to transmit the light beam modulated by the light modulation device;
• and
• a projection optical device adapted to project the light beam transmitted through the light transmissive substrate,
• wherein the light modulation device includes a first light modulation unit having a plurality of pixels arranged, the pixels having colors different from each other,
• the light transmissive substrate is disposed so as to be tilted with respect to an imaginary plane perpendicular to a light axis of the light beam modulated by the first light modulation unit, and is formed of a reflective polarization plate,
• the plurality of pixels is arranged so that pixels with the same color are arranged side by side along a first direction and pixels with different colors are arranged side by side along a second direction perpendicular to the first direction, an astigmatism in the second direction being larger than an astigmatism in the first direction,
• the light transmissive substrate is parallel to a plane obtained by rotating the imaginary plane around an imaginary straight line extending along the first direction, and
• the reflective polarization plate is configured to reflect the light beam of a first linearly polarized light having a first polarization direction along the first direction and is configured to transmit the light beam of a second linearly polarized light having a second polarization direction along the second direction.
